datefmt_set_timezone
( IntlDateFormatter $fmt
, mixed $zone
) : bool
Sets the timezone used for the IntlDateFormatter. object.
参数
fmt- The formatter resource.
zone- The timezone to use for this formatter. This can be specified in the following forms:
null, in which case the default timezone will be used, as specified in the ini setting date.timezone or through the function date_default_timezone_set() and as returned by date_default_timezone_get().- An IntlTimeZone, which will be used directly.
- A DateTimeZone. Its identifier will be extracted and an ICU timezone object will be created; the timezone will be backed by ICUʼs database, not PHPʼs.
- A string, which should be a valid ICU timezone identifier. See IntlTimeZone::createTimeZoneIDEnumeration(). Raw offsets such as
"GMT+08:30"are also accepted.
返回值
Returns true on success and false on failure.
范例
Example #1 IntlDateFormatter::setTimeZone() examples
<?phpini_set('date.timezone', 'Europe/Amsterdam');$formatter = IntlDateFormatter::create(NULL, NULL, NULL, "UTC");$formatter->setTimeZone(NULL);echo "NULL\n ", $formatter->getTimeZone()->getId(), "\n";$formatter->setTimeZone(IntlTimeZone::createTimeZone('Europe/Lisbon'));echo "IntlTimeZone\n ", $formatter->getTimeZone()->getId(), "\n";$formatter->setTimeZone(new DateTimeZone('Europe/Paris'));echo "DateTimeZone\n ", $formatter->getTimeZone()->getId(), "\n";$formatter->setTimeZone('Europe/Rome');echo "String\n ", $formatter->getTimeZone()->getId(), "\n";$formatter->setTimeZone('GMT+00:30');print_r($formatter->getTimeZone());

Europe/Lisbon
DateTimeZone
Europe/Paris
String
Europe/Rome
IntlTimeZone Object
